Section 3 Exception Handling
3.4.2
Each on-chip peripheral module has a flag to show the interrupt request status and the enable bit to
enable or disable the interrupt. For timer A interrupt requests and direct transfer interrupt requests
generated by execution of a SLEEP instruction, this function is included in IRR1 and IENR1.
When an on-chip peripheral module requests an interrupt, the corresponding interrupt request
status flag is set to 1, requesting the CPU of an interrupt. These interrupts can be masked by
writing 0 to clear the corresponding enable bit.
3.4.3
Interrupts are controlled by an interrupt controller.
Interrupt operation is described as follows.
1. If an interrupt occurs while the NMI or interrupt enable bit is set to 1, an interrupt request
